Adding chocolate amps up this iconic minty shake. Since the chips in the ice cream get pulverized in the blender, we've added extra to give the shake a little texture and a more pronounced chocolate flavor.

For a sophisticated spin on the classic St. Patrick's Day milkshake, we've added Bailey's Irish Cream and matcha, which is made from finely ground green tea and has an herbaceous and earthy flavor. If you can't find matcha powder, use green tea ice cream in place of the vanilla.
